# This makefile assumes that you checked out llvm in a subdirectory of your
# home directory called 'llvm'.  The source of llvm itself should be one level
# deeper at ~/llvm/llvm.  It also assumes that you also have the clang component
# of llvm installed.
# It further assumes that clang has been built in Debug mode following the
# usual instructions, with a build directory parallel to the llvm directory.
#   See instructions here:  http://clang.llvm.org/get_started.html
# If you didn't configure Clang this way, you can set environment variables
# appropriately to work with your configuration of Clang and LLVM.
